A look at the question, however, shows not a great understanding of the problem. Specifically, the part of the code that sends the request, and the part of the code that populates the div alone is sufficient. It's quite a task to go through the Wall Of Code and make sense of it.

The OP wants to award a bounty to:

[...]that user who can help me to modify my program to facebook like multi
client chat.

My question is twofold, and it is opinion based:

My understanding is that SO is meant to be a problem-solution site that can help the community as a whole. Are 'Help make this work!' types useful? How will a new coder facing the problem ever find this? Or is the community expected to clean up the question and make it easier to find + answer (which is what we do many times).

Opinion based Aren't questions like this, where bounty is used as a bribe to get people to answer despite a lack of effort, harmful for the site? Seeing as adding a bounty seems to be willful circumvention of rules to ensure site integrity, can we look at this as something worthy of additional penalty?

Feature proposal - Can we have a downvote for bounty specifically for when the community feels that bounty is being used as encouragement to answer not-very-useful stuff? In other words, Can we Downvote the usage of Bounty?

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

This is an interesting point of view. To go further, maybe the possibility to open a bounty should be reviewed by trusted users first. So the OP starts a bounty, and this bounty is only public once it gets enough votes.

Thanks @gnat. I've still not got the hang of searching for questions, clearly! I will edit to reflect that one part is addressed by the prev Q

Shouldn't we catch it before it becomes a problem, and a easy way to game SO into a mechanical trunk? Also, acting quicker may avoid "But it's been like this and it works!" upheavals :)

Amazon Mechanical Trunk is a crowdsourcing Internet marketplace that enables individuals or businesses (known as Requesters) to co-ordinate the use of human intelligence to perform tasks that computers are currently unable to do - Wikipedia
